Facebook Catalog data feed file upload error: image_link: URL Incorrectly Formatted

I’m using Pixel Caffeine to upload WooCommerce products to Facebook Commerce Catalog.
[Possible] fix from Pixel Caffeine
“You have some sort of caching. In this case, make sure every cache you have (from WordPress or from the hosting) are flushed.”

“Temporary deactivate [SG Optimizer plugin] and try to refresh the product feed in order to see if the issue is fixed, just to confirm that that plugin is the cause.”

Purge Cache
In my case, I purged the cache in SG Optimizer WordPress plugin:
- WordPress admin
- SG Optimizer
- SUPERCACHER SETTINGS tab
- Click “PURGE CACHE” button

Refresh Product Feed
- WordPress admin
- Pixel Caffeine
- Product Catalog tab
- Click “REFRESH NOW” button

Re-upload Facebook Catalog Data Source Feed
- Facebook Business Suite
- Commerce
- Catalog
- Data Sources
- Data Feeds section
- Click Data Feed link
- Click Overview tab
- In Next Upload section, click “Upload Now” button
- In Schedules section, click “Request Update Now” button
- A green dot should now appear after “… products updated or added” in Upload Sessions Result section



After re-uploading Facebook Commerce Catalog Data Sources Feed, a GREEN light should appear in the Upload Sessions Result section (see image above).
FINAL
I still need to confirm that this fix allows Facebook to auto-upload the Feed every 24 hours.
